To all whom it may concern:

Be it known that we, JOHN P. Genny and JnrrnnsoN S. Lowarnx, citizens ofthe United States, and residents of Elmira Heights. in the county ofCheinung and State of New York, have invented certain new and usefulImprovements in Yarn- Cleaners, of which the following is aspecitication.

Our invention relates to devices for removing slubs, burs, and the likefrom yarn, in the process of manufacture of the yarn.

One object of the invention is to produce a simple and eflicient deviceof this character which shall operate without subjecting the yarn to anysubstantial tension in its passage through the machine, and to this endwe impart a continuous movement to one of the cleaningblades, andthereby cause the blades to remove imperfections from the yarn by thepower of the moving blade rather than by the power applied to the yarnto draw it through the machine.

Another object of the invention is to produce a yarn cleaner which shallbe adjustable to operate upon yarns of different sizes, and to this endwe employ an arrangement of blades and yarn support having provision foradjustment in several directions, which will be hereinafter moreparticularly de scribed.

Other objects and features of the inven tion will be disclosed inconnection with the following descripthm of the illustrated embodimentof the invention.

In the accoin mnying d 'awings, which illustrate the preferredembodiment of our invention, Figure 1 is a front elevation of a completeyarn-cleaning machine; Fig. 2 is a side elevation shown in section onthe line 2 2 in Fig. 1, looking from left to right; Fig. 3 is a verticalaxial section of the operative ii'lstrumentalities of the machineillustrated in Fig. 1, looking from front to rear; Fig. 4tis a sectionon the line l-l in Fig. 2, looking from above, and showing the operativeinstrumentalities of the machine; Fig. 5 is a detail view of the sameparts, looking in the same direction as in Fig. i, but shown in full;Fig. 6 is a side elevation of the yarn guide; Fi 7 is a section of theyarn guide on the line 7-7 in Fig. 6, looking from above; and Fig.8 is aplan view of the yarn guide.

The operative instrumentahties of the illustrated embodiment of ourinvention comprise two blades and a yarn guide. The blades have edges 5and 6 of generally-cylindrical form, and one of the blades, designatedby the reference number 1, is fixed, while the other blade 3 rotatesabout its cylindrical axis.

The yarn guide 8 is mounted within the cylindrical edges of the blades,as shown particularly in Figs. 3 and a. The edge 6 of the rotary bladeis continuous, but the edge 5 of the fixed blade is cut away at twopoints, and 15, to form inclined portions, as shown particularly in Fig.5. These inclined portions form acute angles with the edge of the.rotary blade, and at the points 18 and 16 where the inclined portions ofthe edge 5 terminate the blades 001110 almost into contact with eachother. The yarn occupies a position within the edges 5 and 6 while it isbeing operated upon, and it enters this space at the part 12of the fixedblade, where the space between the edges is sufficient to permit itsentrance. At this point the yarn guide 8 is provided with a slot 11which guides the yarn, and permits it to move clear of the edges of theblades until it reaches the upper end of the slot. This slot is of awidth substantially equal to the diameter of the yarn, and it operatesto force slubs or wood fibers and other imperfections in the yarnoutwardly toward the edges of the blades. The depth of the slotgradually dilllll'llSflGS to its upper end, so that the bottom of theslot makes an. acute angle with the blade edges, and after the yarnleaves the slot, it moves upon a smooth cylindrical portion 9 of theyarn guide which approaches close to the edges 5 and 6 at the point 13where they come close to each other. The space between the part 9 of theguide and the blade edges is sufllcient to receive the body of the yarn,but the imperfections projecting outwardly therefrom are drawn betweenthe edges, and project wholly outside of the edges, and at the point 13they are securely held by the edges. Beyond this point a second slot H:formed in the top of the yarn guide, this slot being merged graduallyinto the surface 9, as shown in Fig. 6. and the yarn in entering theslot, is drawn gradually away from the edges, so as to be separated fromthe imperfections which are held by, and upon the outer surfaces of theblades. The yarn, after passing through this slot, passes over anothersmooth cylindrical portion 10 of the guide, which brings it again intooperative relation with i the blade edges at the point 16, so that thecleaning operation is repeated. The yarn then passes into a third slot18 in the yarn guide, from which it issues through a lateral opening 19in the fixed blade. A notch 20 in the fixed blade serves as aguide tothe yarn as it issues from the machine.

To permit the rotary motion of the movable blade 3, by which the abovedescribed operation is facilitated, the blade is mounted upon a shaft 21journaled in the frame 22 of the machine. A pulley 23, fixed to theshaft, is connected with any suitable source of power, and is rotated inthe direction indicated by the arrows in Fig. 1, so as to.

cause the edge of the blade 3 to move in the same direction in which theyarn moves through the machine, but at a higher speed.

The fixed blade 1 is mounted, for convenience, upon the shaft 21, but issecured against rotation by means of a pin 24 engag ing a slot in theframe 22.

To insure against breakage of the yarn, which might occur in case aparticularly large or hard obstruction were to resist the action of theblades, the fixed blade is inounted yieldingly to permit it to slideupon the shaft 21 away from the rotating blade. To this end a sprin 26is interposed between the fixed blade and the frame 22. The normalposition of the fixed blade is controlled, however, by an adjustingscrew 28, having a beveled end which engages a beveled collar 27 on thefixed blade. By means of this screw the fixed blade may be adjusted uponthe shaft 21 until its edge comes close to the edge of the rotary blade,as is desirable for the best operation, but without permitting the edgesto actually engage each other. lVhen the blades are sharpened, they maybe readjusted by means of the screw 28 to preserve the proper relativeposition of their edges.

In order to adapt the machine to operate upon yarns of differentdiameters, it is necessary to adjust the distance between the smoothportions 9 and 10 of the yarn guide and the inner surfaces of the bladeedges. To this end the yarn guide is attached to the fixed blade 1 by ascrew threaded in the yarn guide and passing through a slot in the fixedblade. The yarn guide is also provided with an opening 82, through whichthe shaft 21 passes, this opening being larger than the shaft to permittransverse movement of the yarn guide. The adjusting device for the yarnguide comprises a stem 29 journaled in the fixed blade, and having aneccentric portion 30 engaging a hole in the yarn guide. A milled headSlon the stem 29 is used to turn the stem. lVhen it is necessary to adjustthe yarn guide, the screw 25 is loosened and the head 31 is turned,thereby raising or lowering the yarn guide and moving the smoothportions 9 and 10 of the guide simultaneously, and to substantiallyequal degrees, toward or from the inner surfaces of the blades. Thisadjustment is preferably so made as to leave a space between the yarnguide and the blade-edges substan tially equal to the diameter of theyarn.

In addition to the parts above described, the machine is provided with atension device 33, of well known form, for maintaining the propertension on the yarn during its passage through the machine, and from thetension device the yarn passes around a hook 34c and thence to theblades. The 1na chine is not provided with means for drawing the yarnthrough the operative instrumentalities, as it is intended to be used inconnection with ordinary spooling or winding devices of any suitableform.

The rotation of the movable blade of our machine not only facilitatesthe removal of imperfections from the yarn, but it also facilitates thepassage of the yarn through the machine, so that it is not necessary tosubject the yarn to any substantial tension beyond what is required tokeep it taut between the machine and the reel or spool upon which it iswound. In this way, breakage of the yarn, such as frequently occurs inother yarn cleaning machines, is avoided, and the yarn is not subjectedto any harmful stretching. The particles removed from the yarn issueupon the outer surfaces of the blades, and, by. the rotation of themovable blade, they are thrown off from the machine, so that the machinedoes not become clogged during longcontinued operation.

\Vhile the edges of the blades are shown as beveled so as to be thin attheir extremities, it is not necessary that the edges be very sharp,since the rotation of the movable blade so facilitates the operation ofthe blades that they are effective even though dull. F or the samereason it is not neces sary to sharpen the edges often.
